Abstract
This study reveals the fabrication of a gas sensor with a PEDOT:PSS/graphene ink composite as an active layer on glossy paper. The glossy paper was chosen as the substrate material due to its low cost and easy availability. PEDOT:PSS/graphene ink was synthesized by simple mixing of PEDOT:PSS and graphene solution in the presence of distilled water, ethanol, glycerol, and diethylene glycol and was then sonicated and stirred at room temperature and characterized by FTIR, UV, XRD, AFM, and SEM. The sensitivity of the gas sensors towards acetonitrile, propanol, butanol, benzene, methanol, and ammonia analytes was investigated by measuring the change in resistance using a conventional multimeter at room temperature. The results exhibited that the composite’s response to ammonia change is stable and can measure concentration were the results also indicate that the sensors show promising responses with ± 1% reading error with a high response percentage.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
